<p><table width="700"><tbody><tr align="center"><td align="center"><p class="c2" align="left">Select the box with the geometry that you would like to calculate. The round-wire geometries are loops of wire with various shapes. The transmission line geometries are cross sections and the values calculated are the inductance per unit length.</p><p class="c2" align="left">In all cases, the current is assumed to flow in the outer surface of the conductors. The approximate formulas used to calculate the inductance are provided along with restrictions on the relative size of the various parameters. These formulas can be found in various texts and most of them are derived in the book "Inductance Calculations" by F. W. Grover.</p><p> </p></td></tr><tr align="center"><td align="center"><table cellpadding="2" border="2"><tbody><tr><td valign="middle"><h5>Round-Wire Loop Geometries</h5></td><td rowspan="6"><img height="10" alt="blank space" src="http://www.cvel.clemson.edu/emc/images/spacer.gif" width="10" border="0" /></td><td valign="middle"><h5>Transmission Line Geometries</h5></td></tr><tr valign="bottom"><td align="center"><img height="200" alt="square loop" src="http://www.cvel.clemson.edu/emc/new-induct/pics/square.gif" width="250" border="0" /> <p>Square Loop</p></td><td align="center"><img height="135" alt="two separate wires" src="http://www.cvel.clemson.edu/emc/new-induct/pics/wire2.gif" width="250" border="0" /> <p>Twin Lead</p></td></tr><!--============================================--><tr><td align="center"><img height="200" alt="rectangular loop" src="http://www.cvel.clemson.edu/emc/new-induct/pics/rect.gif" width="250" border="0" /> <p>Rectangular Loop</p></td><td align="center"><img height="200" alt="a wire over a ground plane" src="http://www.cvel.clemson.edu/emc/new-induct/pics/gwire.gif" width="250" border="0" /> <p>Round Wire over a Ground Plane <!--============================================--></p></td></tr><tr><td align="center"><img height="200" alt="circular loop" src="http://www.cvel.clemson.edu/emc/new-induct/pics/circle.gif" width="250" border="0" /> <p>Circular Loop</p></td><td align="center"><img height="200" alt="two vertically seperate traces" src="http://www.cvel.clemson.edu/emc/new-induct/pics/trace-v.gif" width="250" border="0" /> <p>Two Vertically Spaced Traces</p></td></tr><!--============================================--><tr><td align="center"><img height="200" alt="equilateral triangle loop" src="http://www.cvel.clemson.edu/emc/new-induct/pics/e-trial.gif" width="250" border="0" /> <p>Equilateral Triangle Loop</p></td><td align="center"><img height="200" alt="A Trace over a Ground Plane" src="http://www.cvel.clemson.edu/emc/new-induct/pics/gtrace.gif" width="250" border="0" /> <p>Wide Trace over Ground Plane <!--============================================--></p></td></tr><tr valign="bottom"><td align="center"><img height="200" alt="Isosceles Triangle Loop" src="http://www.cvel.clemson.edu/emc/new-induct/pics/is-trial.gif" width="250" border="0" /> <p>Isosceles Triangle Loop</p></td><td align="center"><img height="134" alt="two horizontally separated traces" src="http://www.cvel.clemson.edu/emc/new-induct/pics/trace-h.gif" width="250" border="0" /> <p>Coplanar Traces</p></td></tr></tbody></table></td></tr></tbody></table></p> 感谢楼主提供的资料，不过是否能把相应情况下的电感计算公式也提供一下呢？
